Benefits of technology

The present invention is about an ink composition that can be cured by energy rays. The inventors have done extensive research on pigments and found that using specific quinacridone pigments can create unsurpassed color reproduction and storage stability. The aim is to provide an excellent inkjet ink that meets these standards.

Problems solved by technology

Therefore, the dispersibilities of pigments decrease, and thus it is difficult to obtain desired color regions even if similar pigments to those of Patent Documents 1 and 2 are selected.
However, a pigment dispersion using a solid solution is poor in storage stability.
In addition, an active energy ray-curable inkjet ink using a solid solution tends to offer a slow curing velocity during printing.

Abstract

The present invention provides an active energy ray-curable inkjet magenta ink composition that achieves excellent color reproducibility and is also excellent in storage stability, and an ink set using the composition. The magenta ink composition according to the present invention contains, as two kinds of quinacridone pigments, (A) unsubstituted quinacridone and (B) 2,9-dimethylquinacridone.

Description

TECHNICAL FIELD[0001]The present invention relates to an active energy ray-curable inkjet magenta ink composition comprising two kinds of quinacridone pigments, that is (A) unsubstituted quinacridone and (B) 2,9-dimethylquinacridone. The above-mentioned magenta ink according to the present invention offers a broad color reproduction region and has fine storage stability.BACKGROUND ART[0002]Various ink compositions such as solvent types, aqueous types and oil-based types have been conventionally known as inks used in inkjet printing. Among these, the demand for active energy ray-curable inkjet inks has increased in recent years due to their advantages that they can also be applied to no-absorbable substrates such as plastics and glasses, and that they decrease the volatilization volumes of solvents and thus are environment-friendly. Specifically, in the field of industrial inkjet printing, substitution of solvent type and aqueous type inkjet inks with active energy ray-curable inkjet...
